Western Australian Weeds Conference 2009

Land and Water Australia in conjunction with the Weed Society of  Western Australia invite you to present your work at the Western Australian Weeds Conference on the 23-24 September 2009. The Conference will cover a broad range of significant outcomes from the Defeating the Weed Menace initiative.

A virtual farming experience

Lawry Pitman is a farmer from Corrigin in Western Australia. Lawry served his community for many years at the national, state and local levels on community, industry and government committees covering topics as diverse as land management, farm safety and commodity groups.

Improving Soil Health in Western Australian Farming Systems

The crop yields in many shires within Western Australia yield below expectation. Often, this is due to soil contraints. So in order to better-manage soil resources, the severity and extend of underlying soil health problems must first be identified.

New paradigms to find solutions to intractable natural resource management problems

This final report presents the results of the project conducted from 1 July 2005 to 3 July 2008. The project consisted of three phases: firstly, the investigation of personality types of people involved with natural resource management and policy acros

Water resources in a changing climate: central west Western Australia

Communicating Climate Change - Module 11

Water availability is a key issue in Australia. A changing climate will place greater demand on water resources. We need to factor the risks associated with climate change into the ways we use water. Key facts Around 89% of Australia’s total rainfall evaporates or is transpired by plants into the atmosphere. Only around 9% runs off into streams, rivers and storages. The remaining 2% drains below the root zone into groundwater aquifers and, from (more)...

Farm-level adaptation options: North East Agricultural Region, Western Australia

Communicating Climate Change - Module 16

As Australia’s producers continue to be challenged by increased climate variability and climate change, seeking out region-specific adaptation options is important to ensure regional productivity. Understanding which adaptation options to pursue in response to climate change remains a challenge, due to uncertainty about the full extent of future climate change, the response of different crops, and future commodity prices and input costs. Combining expert farmer knowledge with both crop (more)...

Wheat and sheep production in a changing climate: Western Australia

Communicating Climate Change - Module 4

Australia’s wheat - sheep production zone covers 35 million hectares in southern and eastern Australia. Its 15 700 wool-producing farms contain 55% of the nation’s sheep. Annual rainfall in the zone is 300–600 mm. Climate change threatens the productivity of Australia’s wheat and sheep industries. It reduces the value of historical climate knowledge and increases uncertainty about the bounds of future climates, making farm decisions more complex. While (more)...

Glimpsing Western Australia’s future climate

Communicating Climate Change - Module 3

Climate change projections indicate that Western Australia’s climate in the decades ahead will be different to that of the past. Farmers will need to modify their practices to manage the risks presented by the change in climate.

Observed climate change: Western Australia

Communicating Climate Change - Module 3

Western Australia’s climate is changing. Farmers have long been aware of natural cycles in the climate, but now human-induced climate changes are also becoming apparent. These changes will have significant impacts on the way Western Australia is farmed.

Weather drivers in Western Australia

Communicating Climate Change - Module 1

The driving force behind our weather is the general circulation of the atmosphere, caused by unequal heating of the Earth’s surface. Energy from the sun causes uneven heating of land and sea surfaces near the equator and evaporation from tropical oceans. An extensive area of high pressure, known as the sub-tropical ridge, is a major feature of the general circulation of our atmosphere. This belt of high pressure encircles the globe at the middle latitudes. The position (more)...
